IBM researchers have developed granular microcomputers that could work with a blockchain electronic ledger to verify and track any product from its point of origin to merchants all over the world.
These cryptographic anchors (crypto-anchors) could be embedded in everyday objects and devices, says Arvind Krishna, head of IBM Research.
The crypto-anchors would serve as mobile sensors or transmitters with unique hashes to authenticate a product's origins and contents, ensuring it matches the electronic blockchain record. For liquids or metals that can expand with heat, the crypto-anchors can employ a special optical device and artificial intelligence algorithms to identify an object's optical structure and features.
The technology also identifies the presence of DNA sequences in minutes, IBM says.
The product-tracking technology will enable new ways of handling food safety, documenting the authenticity of manufactured components, tracking genetically modified products, identifying counterfeit objects, and protecting luxury goods, says Krishna.
